Title: Manufacture of chloracetaldehyde
IPC: C07C45/00
Filed: 1928-10-22
Abstract: 299,319. I. G. Farbenindustrie Akt.- Ges. Oct. 22, 1927, [Convention date]. Chloracetaldehyde is obtained, without the use of a catalyst, by introducing chlorine gas and vinyl chloride into water, the temperature preferably being kept between 0‹-40‹ C. to avoid the formation of by-products. When the reaction is carried out. at a higher temperature, namely 40‹-80‹ C., it must be interrupted at an earlier stage, to avoid the formation of byproducts, especially chloracetic acid. It is preferable to exclude light, which favours the formation of 1:1:2-trichlorethane. The reaction is practically complete when using molecular proportions and the gases disappear in the liquid; it is therefore preferable to mix one of the reacting gases with an inert gas, such as carbon dioxide or nitrogen, which is not absorbed in the liquid and the bubbles of which assist in mixing the liquor thoroughly. In examples, solutions containing 70-75 per cent of the theoretical yield are obtained.
Patent GB-536686-A (GB)
Title: Improvements in or relating to the treatment of cellulosic textile materials
IPC: D06P1/52
Filed: 1939-11-22
Abstract: 536,686. Dyeing processes; artificial filaments &c. COURTAULDS, Ltd., TALLIS. E. E., and FIELD, W. J. C. Nov. 22, 1939, Nos. 30565/39, 3262/40 and 12065/40. [Classes 2 (ii), 2 (iii) and 15 (ii)] The affinity of cellulosic textile materials for dyestuffs commonly used for dyeing wool and like animal fibres, is improved by incorporating in the materials a compound obtained by the action of an aryl isocyanate or isothiocyanate on a polyalkylene polyamine. The materials may be impregnated with a solution or dispersion of the compound or in the case of artificial threads, the compound may be incorporated in the spinning solution from which the threads are formed. The polyalkylene polyamine which is caused to combine with the aryl isocyanate may be ethylene diamine, trimethylene diamine, triethylene tetramine, tetraethylene pentamine, pentaethylene hexamine, or other polyethylene polyamine, or a compound obtained from any of these substances by further alkylation, e.g. by condensation with an aliphatic alkylating agent containing more than one alkylating group such as α-dichlorhydrin, dichlorethylene, trimethylene bromide; dichlorisopropyl ether, triglycol dichloride, or sym-dichloracetone. or by condensation with an alkylene oxide such as ethylene oxide. The isocyanate or isothiocyanate reaction product may be treated before or after incorporation in the cellulosic material with a halogenating agent such as chlorine, or bromine, or a hypochlorite, or a hypobromite, as this tends to prevent the dye from wandering from the cellulose to other admixed textiles during prolonged dyeing treatment. The treatment with halogenating agent may be combined with a bleaching treatment. In an example, a solution of triethylene tetramine in water is mixed with alcohol and heated under reflux with α-dichlorhydrin to give an aqueous solution of a polyamine compound. The solution is diluted with water and an emulsifying agent and mixed in a pebble-mill with phenylisothiocyanate. The dispersion obtained is mixed with viscose which is then formed into artificial threads which have an enhanced affinity for wool dyes. The resulting threads may be desulphurized and then bleached with hypochlorite solution. In another example, tetraethylene pentamine is heated to 100‹C. and then ethylene oxide is mixed with it under reduced pressure. The compound obtained is dissolved in benzyl alcohol and then phenyl isothiocyanate is added slowly while cooling. The solution is dispersed in viscose which is then extruded into a solution of sulphuric acid containing sulphates and glucose. The threads obtained are de-sulphurized and bleached. Specification 536,687 is referred to.

Abstract: 618,315. Cathode-ray oscillographs. SADIRCARPENTIER. Oct. 15, 1946, No. 30724. Convention date, Jan. 17, 1945. [Class 37] [Also in Group XL (c)] A synchronizing pulse is applied at 1, Fig. 1, to control the time base 2, and is delayed by variable delay network 5 to cut off the signal voltage and produce a deflection to act as a marking pulse, means being provided to produce the marking pulse once only in a plurality of sweeps of the time base. A.C. is applied to valve 18 so that it is conducting for short periods of time to alter the screen voltage of valve 8 and allow it to transmit the delayed pulse to render valve 9 non-conducting and thus displace the cathode ray to the position d, Fig. 2. Signal voltage, e.g. radar echoes c, is applied at 16 and delineated on the screen when valve 9 is conducting. By varying the frequency of the A.C. applied at 22, only every nth delayed pulse is effective, and the underlining d can be adjusted along the trace by varying the tap on the delay network 5.

Title: Process of and means for melting glass, silicates and like mineral substances
IPC: C22B5/00
Filed: 1928-10-24
Abstract: 300,576. Zotos, G. Nov. 15, 1927, [Convention date]. Rotary furnaces.-In the melting of glass, silicates and like mineral substances the materials are fed continuously to a rapidly rotating furnace fired by a gas, oil, or powdered fuel burner, and the molten product is withdrawn from the inner part of the layer of material formed in the furnace. In the apparatus shown the furnace 1 is enclosed within a casing 1<1> through which cooling air is passed, and is fired by a burner 6 passing through a glass collecting space 9 having drawing- hearths 10 connected thereto. The discharge neck 8 of the furnace is cooled by an air jet 15 so that a protective layer of solidified glass is formed thereon. The hot air from the casing 1<1> may be further heated in a recuperator and then used partly for combustion in the furnace and partly for supply to a gas producer, while the waste gases from the furnace may be used partly in the recuperator and partly in an annealing furnace. The air for the combustion furnace is passed over the molten glass in the space 9. The axis of the burner 6 is arranged at an angle or eccentrically to the drum, and the gas is delivered with such velocity that the flame is formed at some distance from the delivery nozzle. The neck through which the molten glass is delivered is notched so that the flow of glass is concentrated at one or two points, and to prevent the viscous stream from winding round the neck the furnace is inclined, or the glass is drawn off immediately on delivery by a drawing-machine, or by cooled suction pipes.
